Abstract

Before a secret information is transmitted, a signal transmission and reception is performed between a first radio station on the secret information transmitting side and a second radio station on the secret information receiving side, thereby estimating a radio propagation path environment shared only by the first and second radio stations. Then, the secret information is transmitted from the first radio station to the second radio station with the foregoing radio propagation path environment taken into account.
